BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 255,870, dated April 4,1882.

Application tiled January 4, 1882. (No model.) y

` To all whom it may conce/rn Be it known that we, PHILIP H. KELLS,ABRAM KELLs, and J ACoB M. KELLs, of Adrian, in the county of Lenaweeand State of Michigan, have invented new and useful Improvements inBrick-Machines; and we hereby declare that the following is a full,clear,

land exact description thereof, reference being had to theaccompanyingdrawings, which form a part of this specification.

The nature of this inventionV relates to certain new and usefulimprovements in the construction of that class of brick-machines knownas horizontal machines, by means ofwhich a greater simplicity andeconomy of construction is had than has heretofore prevailed while agreater strength is obtained.

The invention consists in the peculiar construction of the parts andtheir various combinations, as more fully hereinafter described.

Figure l is a perspective view of our improved machine. Fig. 2 is a topplan of the same with the cap removed. Fig. 3 is a verticalcross-section on the line x x in Fig. 2.

In the accompanying drawings, which form a part of this specification, Arepresents the feet of the machine, cast with and forming an integralpart of the lower half of the tub B, which extends from the master-wheelC tothe flange D, which forms the means, with suitable screws, ofsecuring the die-plate E. The lower half ofthe tub B is preferably inthe form of half of a cylinder split longitudinally, and it is cast withoutwardly-projectin g flanges a and with the semicircular flange D andwith saddles or bearings F, which form bearings in which'the shaft Grevolves, and which are provided with retaining-caps H. Upon the underside of these saddles are cast the diaphragms I, which divide the lowerhalf of the tub into the two chambers J J', asshown in Fig. 2.

The feet A, the lower half, B, of the tub, the anges a a and D, thesaddles or bridges F, and downwardly-projecting diaphragms I are allcast in one piece, whereby great strength is obtained, and the labor andexpense of vtitting and securing the parts together, when castseparately, are avoided. The upper half or cap, of the tub B, and whichis lettered K, is

an outwardly-projectin g flange, b, on each side, which, when the cap isin place, rest upon the iianges a, and the parts are secured together bybolts, as shown in Fig. 1. This cap is also cast with a projectingsemicircular flange. L, to which the upper part of the die-plate E isremovably secured. The cap is also cast with or provided with a hopper,M, at its rear end, and the interior of the cap at this end is cast withan end plate, which is in line with the diaphragm which divides thechambers J and J.

The shaft C is supported in the bearings F F, and projects into the tub,as shown in Fig. 2, and inthe chamber J this shaft has secured to it, inany of the known or convenient ways, the spiral or partially spiralflanges N for grinding the clay introduced into the hopper and forcingit through the dies in proper form for brick or tile. This shaft isdriven by the master-wheel C from any convenient source of power. Toprevent and counteract the backward end-thrust of this shaft, when inoperation, there is rigidly secured to it a collar, 0, which is providedwith a strong outwardlyprojecting flange the rear'face of which bearsagainst they friction rollers or wheels c, which 's of similar form tothe lower half, and is cast with 5o arejournaled in the ends of thebearings R, sui'tably `secured to the rear endof the lower half of thetub and its rear bridge, F;

A washer, S, is interposed between the rear end of the collar O and therear bearin g, which supports the shaft and assists in resisting thisend-thrust with the least possible friction.

The die-plate shown is for the manufacture of bricks; but this may bechan ged for one for the purpose of making tile, if desired.

What we clairn as our invention is 1. In a horizontal brick or tilemachine, the grinding-shaft provided with a flanged collar, incombination with the friction-wheels and their bearings, substantiallyas and for the purposes specified.

2. The shaft G, having spiral leaves N and annular flange, the tub B,master-wheel C, and Washer S, combined with the bearings R andfriction-wheels c, as set forth. i

3. ln a brick-machine, the lower semi-cylindrical casting having endbearings for the op- (arming-shaft, a diaphragm for dividing` the atingniechnism, a die-plate, and semi-cylin- 1o mud-box and to form a recessfor receiving drical cap K, as and for the purpoges set forth. mechanismfor modifying friction and bear- PHILIP H.
